The Forest Service Remote Sensing Applications Center (RSAC) and the U.S. Geological Survey Earth Resources Observation Science (EROS) Data produce Burned Area Reflectance Classification (BARC) maps for use by Emergency Response (BAER) teams in rapid response to wildfires. BAER desire indicative of fire effects on soils, but green nonphotosynthetic vegetation other materials also affect spectral properties post-fire imagery. Our objective was assess how well satellite image-derived burn...
Abstract Post‐wildfire changes to hydrologic and geomorphic systems can lead widespread sediment redistribution. Understanding how moves through a watershed is crucial for assessing hazards, developing debris flow inundation models, engineering retention solutions, quantifying the role that disturbances play in landscape evolution. In this study, we used terrestrial airborne lidar measure redistribution 2016 Fish Fire, San Gabriel Mountains southern California, USA. The areas are two...
Needle cast from partially burnt conifer trees commonly occurs after forest fires. The effectiveness of needles in reducing soil erosion was investigated this study. Two needle types, ponderosa pine and Douglas fir needles, were used at four different cover amounts (0, 15, 40, 70 percent) on granitic volcanic derived soils. Simulated rainfall to examine interrill erosion; added inflow determine rill a laboratory setting. After series “runs,” data showed that sediment delivery greater for the...
Abstract Wildfire is a major ecological process and management issue on western rangelands. The impacts of wildfire hydrologic processes such as infiltration, runoff, erosion are not well understood. Small‐plot rainfall simulation methods were applied in rangeland setting to determine post‐fire response. Infiltration interrill measured immediately one year following the 1999 34 400 ha Denio fire northwestern Nevada. Plot‐scale spatial temporal variability was compared with adjacent unburned...
An important element of evaluating a large wildfire is to assess its effects on the soil in order predict potential watershed response. After 55 000 ha Hayman Fire Colorado Front Range, 24 and vegetation variables were measured determine key that could be used for rapid field assessment burn severity. The percentage exposed mineral litter cover proved best predictors severity this environment. Two classifications, one from statistical classification tree other Burned Area Emergency Response...
Vegetation response and burn severity were examined following eight large wildfires that burned in 2003 2004: two California chaparral, each dry moist mixed-conifer forests Montana, boreal interior Alaska. Our research objectives were: 1) to characterize one year post-fire vegetation recovery relative initial fire effects on the soil surface could potentially serve as indicators of (and thus, ultimately longer-term ecosystem recovery), 2) use a remotely-sensed indicator describe landscape...
ABSTRACI:. Slash burning is a common site preparation technique used after timber harvest throughout the Southeastern United States. Little quantitative information exists on hydrologic response to burn severity. This study compared effects of low‐severity and high‐severity burns runoff sediment yields during rainfall simulation natural in Southern Appalachian Mountains. Fire severity was largely determined by moisture conditions forest floor prior ignition. Runoff yield variability high...
Between 1998 and 2002, six sites were established immediately after large wildfires in the western United States to determine effectiveness of contour-felled log erosion barriers mitigating post-wildfire runoff erosion. In each pair matched, burned, small watersheds (1–13 ha), one was treated with left untreated as a control. For 4 6 post-fire years, sediment yields measured correlated rain properties. High-intensity rainfall produced most except southern California site, where long-duration...
The increasing size and severity of wildfires in the western United States has caused a corresponding increase post-fire emergency erosion control activities. Hillslope treatments, such as broadcast seeding, mulching installed barriers, are applied to reduce runoff erosion, well downslope sedimentation. However, there few data determine if these treatments practical effective. Direct measurement hillslope particularly remote settings where occur, is time consuming costly. Rainfall...
Abstract Post‐fire runoff and erosion from wildlands has been well researched, but few studies have researched the degree of control exerted by fire on rangeland hydrology processes. Furthermore, spatial continuity temporal persistence wildfire impacts are not understood. Small‐plot rainfall concentrated flow simulations were applied to unburned severely burned hillslopes determine fire‐induced interrill rill processes steep sagebrush‐dominated sites. Runoff measured immediately following...
